COTTON TEAMPER.

Application filed March 16, 1926. Serial No. 95,089.

This invention relates to cotton trampers and particularly to those trampers lIl WlHCl'l the plunger is operated by gearing trom a power shaft as distinguished from those which are operated by pneumatic pressure.

The general object of the invention is to provide a tramper whichis entirely automatic in its action and in which so long as it receives power the plunger is caused to alternately move downward and upward.

ll further object is to provide for a proper operation of the cotton feeding means when the plunger is raised and to stop the oper ation of the feeding means when the plunger has be"n depressed a predetermined degree, and another objectin this connection is to provide i leans for automatically applying a brake to the shaft cart g the feeding blades t thereby prevent this shaft from overrun after the plunger has reached a predeteruuncd position,

Other objects will appear in the course of he following description.

l 'v invention is illustrated in the accompanying drawings wherein Figure l is a top plan view partly in section of a cotton tramper constructed in accordance with my invention;

Figure 2 is a vertical sectional. View on the line 2-2 of Figure 1;

Figure 3 is a side elevation of the hand wheel and care;

Figure *1 is a section on the line 4-4 of figure It;

Figure 5 is a section on the line 55 of Figure 1". and

Figure is an elevation of the driving gear wheel for the plunger.

Referring to the drawings it will be seen that the frame of the machine comprises the longitudinally extending beams 10, transverse end beams 11, the vertical supports 12, the lower longitudinal beams 13, and certain cross beams, later referred to.

At one end of the frame and between one of the end beams -ll and the cross beam 14, I provide the two vertically extending guides each guide being fornicdto provide a. guide groove 16. These guide members 'lf are suitably spaced from each other, and operating between these guide members is the plunger, comprising the base or plate 'l'l' and ill! plunger rods l8. spaced front each other and connected by the cross pins .19,

plus 19 constitiutin; a rack to which, v riger proper is attached. The upper ends of the rods are connected by means of a transverse brace 20 which operates within the groove 16, this brace carrying the slides 21 hearing a ainst the walls of the groove fi so that the p unger may operate easily Operating upon the pins 19 and acting to raise or lower the plunger is a gear wheel 22 mounted upon a shaft 23. i This shaft is mounted in suitable bearings upon the 1011- 65 gitudinal beams 10 and carries at its ends the sprocket wheels 24. Extending parallel to the shaft 23 is a shaft 25 which carries at its extremities sprocket wheels 26, which are relatively smaller than the sprocket 70 wheels 94; and engaging these two sprocket wheels are the sprocket chains 27. Mounted upon the shaft 25 are the two oppositely disposed spaced beveled gear wheels 28 and :7

gear wheel rotates with the shaft 80, the teeth a 32 will alternately enguu'e'with one or the other of the beveled gears 28 and 28 and obviously the shaft 25 will be driven alternately in opposite directions by a continuous rotation ofv the bevel gear wheel 31 in one direction. The shaft carries upon it the fast and loose pulleys 33 and St and a belt 35 (transmits powerfrom an; suitable powcr'sbaft to these pulleys and this belt is shifted onto the fast or loose pulleys, as desired, by means of a belt shifter 36 which is slidingly mounted on the frame of the machine and is operated by means of a lever 37.

.For the purpose of feeding; the cotton to the box beneath the plunger 1 provide a chute including the upper and lower downltlll wardly inclined walls 38, and extending beneath these walls is the shaft 39 which carries upon it the diametrically disposed blades 40 which, as this shaft 39 is rotated act to feed the; cotton downward through the chute into the press box but which when the shaft is shifted to a position whore the bladhs are vertical, prevents the discharge of cotton into the press box. l? or the purpose of operating this shaft 89 1 provide the shaft :1! one end with 1 "car in: 2 h Il near who ilwzilimill ;exlcm nurs xiends parallel ii xoi'tiwl in suitable hearings in the iii oi the machine. This shall? carries the fast and loose pulleys 4 and niounled upon The shaft is a hand n from which a belt 46 passes, lo {the his or loose pulleys 4. and ll. It lli that this hell? ll be mmnnnlicnlly sh: 1 the loose pulley hen the plunger liars rl;-- scended to a prerlelei'zninod point lo hereby stop the rotation of the ceiling hlmlcs uni, hold the hludes in position to prevent. the further den-col oil-mien info ihe hozr z. To this end I m unt hencnih the lmznl wheel a hell; shiilm' coir ling prei erohly though not necessarily, metal plate pivoted m; its rear end, as at 8, upon one of the lJCzlillS 2.0 and sit iis forwarder free end having nplorned flanges 49 which en- -ige with the belt 46. This plate i? or hell shifter is provided upon its opposite nisrgins with the upwardly extending" flanges 5G and engageable alternately with these flanges are the earns 51 and The forward ends of these cams are, of course. rounded and the cams are disposed in. a 'rnnsi'ersely' diarnetricsl relation so that 38 the band Wheel 45 rotates in the direction of the arrow in Figure 1, the cam 51 for in stance, will strike the flange on one side of the belt shifter d'lend will shift it in m the J it.

' a direction to carry the belt 46 onto the fast ,ulley 43 and in a, further rotation of the and Wheel the cam 52 will act to shift the belt shifter in the other direction to carry the belt 46 onto the loose pulley 44. Uhvjionsly when the belt has films been 'sl'iilieil, power willhe no longer transmitted to the shaft 42 and the feeding mechanism will come to a stop. Inasmuch as, however, this feeding mechanism would be likely to overrun I provide a brake for this shaft com prising a band 53, passing ,srtinlly around a brake wheel 54 mounted upon the shaft 42, one end of this brake band 52 being c0nnected to the frame of the machine below the pulley 5-"l while its other end passes over a, cam mounted upon the shell: 30, This end of the brake band is engaged lay a con traclile spring 5? which holds the brake band taut against the cam 55. A: the

moment When the Hamper plunger-lia se reached such position that no more cotton is to be fed into the press beneath the plunger, i'he cam 55 is brought to a vertical posifion where it will tighten the hrs-lire band 53 to such an extent as to cause the im mediate stoppage of the shaft l2 Willi ihe blades 40 in a vertical positio. which wil block all passage of colton info the press box. 4

The operation of this mechanism will he rho rainper. llillie ole the inst pulley 43 has been by 'ihe belt 46 with the she ft 30 and as s consemisrce is opcrning (0 feed eotlon into the i loos: through the chute 3B. When the nlnng r has descended n precle- 'le'i rent however and passed he is lihe cam will operate in kl direction to the loose pulls thus, explai cutting oil pone? irom a 4:. and 1mm the feeding shalt this occurs the cam 55 has reached t where it tightens up on the brake has applying the brake to the l preventing further movement .7 and holding he blades -0 into I 1 l. 1 position. They remain in this p sitron until the plunger through the aeiion of he gesrs 31 and 28 has risen a predeiermined nmount and at this time the coin has roinicd sufliciently to slacken the brake end at the same time, the cam 51 sets lo shift the Wheel 47 in s (lirecrion. to cause the belt 46 to shift onto the fast pulley 4-3 thns again operating the feeding mechanism,

it will be seen that this mechanism eniirely automatic in its action and that so long as power is applied to the shaft 30 -the plunger will he intermittently raised and do: pressed and the feeding mechanism will he intermittently operated or stopped. The mechanism is very simple, can be rclaiively cheaply made, has no parts which are liable to get out of order, and maybe made role livelyv light and thus it costs less to manufacture than the ordinary cotton tramper. fine of the particular advantages of the iiwention is that the packer is reversible so that it may work on either side of the press and be 'thns disposed within the peel;- ing house at the most advantageous point. Thus. for inslance, it is only necessary in order to change from one side of the press lo the other to reverse the packer i'o transfer shaft; 1-2 with. pulleys 41, 43 44 and 5% to the opposite side of frame or in other words to the hearing 4-2 in Figure 4 'rhen lransler the shaft 39 with pulleys 40 and blade 40 to the hearing 39" in Figure -l. To transpose the feeding meclmnism. i'rnnsposc the bell shifter 47 lo the opposiic side of the frame their direction on the pulley so as to operate the pulleys &7 and 44; 1n an opposite d1- rection to what they formerly did'and obviously the shaft 30 might operate in an opposite direction to what it formerly did. Thus, a few small changes can be made in my machine to place the operating or controlling mechanism on the opposite side of the press where in other trampers the entire machine must be changed. Obviously, the machine will be made as particularly shown in Figure 4. so as to permit these changes to be made.

1t is to be particularly noted that the feeding mechanism of my tramper is operated by the same mechanism which in turn reciprocates the tramper. Thus, both the feeding mechanism and the tramping mechanism are operated by a single belt where heretofore two drive belts, one for the tramper and one for the feeder, have been used.

I claim 4 1. Mechanism of the character described including a driven shaft having loose and fast pulleys thereon, a drive shafthaving a pulley thereon, a belt connecting the pulley on the drive shaft with the pulleys on the driven shaft, and means whereby to shift said belt from the loose pulley to the fast pulley and vice versa, including a pivotally mounted plate having upturned flanges at one end for engaging the belt, upwardly extending flanges on the plate adjacent the other end, and cams arranged upon opposite sides of the pulley on. the drive shaft adapted to engage the second mentioned flanges on the plate'for imparting lateral movement to said plate whereby to shift the belt from the loose to the fast pulley and vice versa,

2. Mechanism of the character described including a drive shaft, a driven shaft having loose and fast pulleys thereon, a pulle Y on the drive shaft, a belt connecting the pu leys onthe drive and driven shafts, means for shifting said belt from the loose pulley to the fast pulley at a predetermined distance and returning the belt from the fast pulley to the loose pulley, a brake wheel upon the second shaft, a brake band extending over said brake wheeland having one end rigidly supported, a spring exerting ten sion upon the other end of the hand, and a cam upon the drive shaft adapted to exert pressure upon the brake band when the belt upon the drive shaft is shifted from the fast pulley to the loose pulley, as and for the purpose set forth.

ivl'echanism of the character described including a driven shaft having fast and loose pulleys thereon, a drive shaft having a pulley thereon, a belt connecting the pulley on the drive shaft with the. pulleys on the driven shaft, and means for automatically shifting said belt at intervals from the loose pulley to the fast pulley including a pivotally mounted member formed for engagement with the belt, and cams mounted on the drive shaft adapted to alternately engage the said pivoted member to impart lateral movement to said member alternately in opposite directions whereby to shift the belt from the loose to the, fast pulley and vice versa.

In testimony whereof I hereunto afix my signature.
